as i posted the spectrum sensing problem earlier i wanted toknow about the probability of false alarm. i worked out forthe probability of detection and got the curve as given bythe paper of Bhargava et. al. i calculated the probabilityof detection by first finding the individual detection usingenergy detection and then dividing the number of times thedetection is produced with the number of iteration. now iwant to find the probability of false alarm but am notgetting any idea to implement it in matlab. anybody has anyidea to calculate the probability of false alarm. pleasehelp me...thank u
